Common units for electrics:
| Description | Symbol | Unit (symbol) |
|---|---|---|
| Electrical Potential difference | U / V | Voltage (V) |
| Electrical Current | I | Ampere (A) |
| Electrical Resistance | R | Ohm (Ω) |
| Electrical Power (work done) | Watt (W) | |
Ohm’s Law:
Resistance:
Resistors in series add together.
Resistors in parallel add together as the inverse of the individual resistance (1 / R)
